The role of engineering structure waterproofing is to protect the deck and structure from
the corrosive effects of zenithal water, which may also contain aggressive products such as
decicing salts used on pavements in winter.
Laying a waterproof screen on a concrete deck can sometimes produce unwanted side effects.
Because of the microporosity of the concrete, air and water can become trapped under the
waterproofing and air and steam escaping from the concrete can produce blistering that can
damage the waterproofing and the surface course.
The new Viaplast® process developed by Eurovia eliminates the risk of blistering and can be applied at high output rates.

Concrete cloth is a ground breaking material technology that allows concrete to be used in completely new ways. It is a flexible cement- impregnated fabric that hardens on hydration to form a thin, durable water proof and fire proof concrete layer
The vacuum dewatering process basically improves strength, durability, and other properties of concrete by reducing the water-cement ratio immediately after the mix is placed, usually in floors and other flatwork.

Internship project on Concentric Annular Pack Screen System (CAPS) at Hallibu...OmokpariolaElshalom
Concentric Annular Pack Screen System (CAPS) is the model way of handling sand control in hydrocarbon exploitation. This has been proven to outsmart the Gravel Packing and frac-packing technique as it is composed of three types of annular systems suitable for sand control, thereby preventing the blockage of pipes in drilling.
This method is intended for the passive sampling of Volatile Organic Compounds (VOCs) in ambient air and soil gas - using Waterloo membrane samplers (WMS’). This method is a guide on the installation process for WMS’ and does not purport to address all of the aspects of site assessment such as implementation of sampling pattern, sampling density/frequency, data interpretation, modelling, outside influences or technical issues.
Effect of Sand invasion on Oil Well Production: A Case study of Garon Field i...theijes
The effect of sand and other BS&W invading the wellbore of an oil well has been studied using Garon field in the Niger Delta region. Garon field has unconsolidated formation and it has been producing for more than 10 years. This study is carried out to quantify the safety and economic effect of sand invasion on well productivity and not on the techniques in numerical models for the prediction of sand production. It tries to look out the sand evolution, analysis of previous well test done and a survey of sand identification, results of some wells production data and evaluation of the effect of sand invasion on subsurface and surface production facilities. In this study, Well X17 was routed into a test separator for 3days and immediately tested for 72hours. The test separator man way opened in other to ascertain the quantity of sand produced from the well for 72Hrs to validate the result obtained with Clampon DSC. Also presented are the effects of sand invasion on surface facility, choke, screen and tubing.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Quality defects in TMT Bars, Possible causes and Potential Solutions.PrashantGoswami42
Maintaining high-quality standards in the production of TMT bars is crucial for ensuring structural integrity in construction. Addressing common defects through careful monitoring, standardized processes, and advanced technology can significantly improve the quality of TMT bars. Continuous training and adherence to quality control measures will also play a pivotal role in minimizing these defects.
Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
2. WHAT IS V-PROCESS
This is yet another moulding process which
doesn’t need any chemical or organic binders
in the sand for moulding. One of the foundry
which adopted VPC in India could envisage to
double its moulding capacity in 2 years’ time,
after all his process cost had become
economical by 20-25% by adopting this
process.
3. WHO SHOULD TARGET FOR VPC
Foundries which are into Railway Castings in India
making Side Frames, Bolsters for Casnub Bogies,
Coupler etc and CMS Crossings should immediately
target to reduce sand cost and shop-floor related
pollution in their foundries.
Foundries making large wear resistant Mn-Steel
castings like Jaw Plates, Blow-Bars, Cone and Mantel
should reduce their cost of resin sand usage and cost of
Primary, Secondary Attrition and Thermal Reclamation
and related manpower and maintenance costs.
4. V-PROCESS STEPS
1. THE PATTERN (WITH VENT HOLES) IS PLACED ON
A HOLLOW CARRIER PLATE.
2. A HEATER SOFTENS THE 0.07 TO .0.2 MM EVA
(ETHYLENE-VINYL ACETATE) PLASTIC FILM. EVA
PLASTIC HAS GOOD ELASTICITY AND A HIGH
DEFORMATION RATIO.
3. SOFTENED FILM DRAPES OVER THE PATTERN WITH
0.03 TO 0.05 MPA VACUUM ACTING THROUGH
THE PATTERN VENTS TO DRAW IT TIGHTLY
AROUND THE PATTERN.
4. THE FLASK IS PLACED ON THE FILM-COATED
PATTERN. FLASK WALLS ARE ALSO A VACUUM
CHAMBER WITH THE OUTLET SHOWN AT RIGHT.
5. THE FLASK IS FILLED WITH DRY, UN-BONDED
SAND. A SLIGHT VIBRATION COMPACTS SAND
TO MAXIMUM BULK DENSITY.
6. A SPRUE CUP IS FORMED AND THE MOULD
SURFACE LEVELLED. THE BACK OF THE MOULD IS
COVERED WITH UNHEATED PLASTIC FILM.
5. V-PROCESS STEPS
7. VACUUM IS APPLIED TO THE FLASK.
ATMOSPHERIC PRESSURE THEN
HARDENS THE SAND.
8. THE COPE AND DRAG ASSEMBLY
FORM A PLASTIC-LINED CAVITY.
DURING POURING, MOULDS ARE KEPT
UNDER VACUUM.
9. AFTER COOLING, THE VACUUM IS
RELEASED AND FREE-FLOWING SAND
DROPS AWAY LEAVING A CLEAN
CASTING, WITH NO SAND LUMPS. THE
SAND IS COOLED FOR RE-USE.
6. BENEFITS OF V-PROCESS
Reduction in Sand Consumption
99%
No water, no binder and no
additives in Sand
Cost reduction by about < 20%
Very Smooth Surface Finish 120 RMS
Excellent Dimensional Accuracy
Zero Draft
Thin Wall Sections Possible
Excellent Reproduction of Details
Increased Pattern Life (no wear of
pattern)
Very Easy Knock-out, within no time.
No sand sticking or inclusion
No toxic fumes from burning the
binders
Excellent sand permeability
Moisture related casting defects is
zero.
Yield increases.
